Iupiace, LEMALLOY, Modified polyphenylene ether resin

Iupiace (modified PPE resin) is an amorphous engineering plastic, which is developed by Mitsubishi Gas Chemical Co., Inc., with its unique technologies and whose main components are the polyphenylene ether (PPE) and polystyrene (PS). It has a good balance of electric property, flame resistance, heat resistance, dimensional stability, moldability, and other properties.
Additionally, its specific gravity is the lowest among engineering plastics. It is UL-approved and is used for the mechanism parts of home appliances and in electric/electronic office automation equipment, such as the chassis of office automation equipment. It is also used for a wide range of applications, such as automotive exterior parts and water related parts, including pumps by taking advantage of its hot water resistance.
LEMALLOY has sea-island structure. Matrix phase is crystalline resin, such as a polyamide resin (PA) or polypropylene resin (PP) and domain structure (in the matrix phase) is polyphenylene ether resin (PPE). This resin has the chemical resistance and moldability/workability of a crystalline resin and the dimensional stability and stiffness at high temperature of an amorphous resin together. It is therefore used in various environments. In automotive applications, it is frequently used for electric components, such as the junction box and connectors in an engine compartment, by taking advantage of the chemical resistance of a crystalline resin and the characteristics of PPE, such as low specific gravity and low water absorption.
